,ALONZO LINTON BAUSMAN, OF SPRINGFIELD, MASSACHUSETTS, ASSIG-NOR TO N ATIONAL EQUIPMENT COMPANY, OF SPRINGFIELD, IvIASSAGI-EUSETTS, IL CORPORA- TION OF MASSACHUSETTS CONFECTION COATING AND DECORATING MACHINE Application filed March 15, 1928.

This invention relates to improvements in machines for coating and decorating confections and the like.

The invention in some respects, is an improvement on that disclosed in my U. S. Letters Patent No. 1,571,365, dated February 2, 1926. The machine of said patent functions in a lniown way to coat the confections but differs from general practice in the manner of delivering the coated confections from the machine. The characterizing difference is that the freshly coated confections are allowed to travel along with the coating machine conveyer while the latter passes from its upper toits lower stretch of travel, instead of being removed from the conveyor at the end of its upper stretch of travel, as is usual. The confections then drop from the lower stretch of the conveyor and fall upon an underlying delivery conveyer. That in vention was directed primarily to the problem of transferring small confections, such as raisins, peanuts and the like, from the coating conveyor to the delivery conveyor. Incidentally, however, each confection as it falls from the conveyer, to which it has been clinging by reason of its viscous coating, draws out part of the coating into a string and one problem of this invention is to provide means for controlling the formation of such strings so that they may be utilized in a. commercially satisfactory way as decorations. 1

Another problem of this invention is to preserve the decorations after they have been made in the described manner, until the coating have hardened. It is necessary to avoid a condition such that one confection can fall on top of another. Such a condition exists where the delivery belt and the lower stretch of the coating machine move in opposite directions. In the machine of the aforesaid patent, this objectionable arrangement of belts was used but means were provided which tended to offset the trouble. Such means consisted of an arrangement for knocking each confection off the belt when it arrived at a predeterminedv point in the lower stretch of travel of the belt, rather than to allow the confections to drop off an Serial No. 262,010.

assisted and in an uncontrolled manner. However, since the confections are bound to vary in size and in weight and since the viscosity of the coating may vary, it is difiicult to control the knocking off action with precision under all of the various conditions which are encountered in commercial practice.

Therefore, for insurance against any possibility of trouble from the source just described, the delivery conveyer, according to this invention, is made to travel in the same direction and at substantially the same speed as the lower stretch of the coating belt. Then confections can drop off the coating belt at any point within reasonable limits and the particular point at which the confection drops from the coating belt will not matter for there will always be an underlying space on the delivery belt to receive it. The rapping means is no longer essential although it may, if desired, be used. With this arrangement of the two conveyers, the confections always take the same orderly arrangement on the delivery conveyor as they did on the coating conveyor and by no possibility can two confections be superposed or stick together.

This arrangement, however, makes it necessary for the delivery conveyer to extend back through the heated casing of the coating machine along a level beneath the coating belt. For the proper preservation of the decorations of the confections, it is essential to protect them from the heat of the coating machine. Otherwise, the decorations, especially in their extremities and in the finer parts of the strings, would be melted to an extent sufficient to destroy their attractiveness. Also, provisions must be made for preventing chocolate which drips through the previous coating belt, from lodging on the delivery conveyor and the decorated confections carried thereby.

This invention has for objects the provision of improved means for decorating confections in the manner described; for controlling the formation of the decorations and for varying the designs thereof; for preserving the decorations during their return travel through the coating machine; and for providing for the return of chocolate from the coating means to the underlying supply tank along and beyond a side edge or edges of the delivery conveyer.

These and other objects will more particularly appear in the following description and will be pointed out in the appended claims.

The invention will be disclosed with reference to the accompanying drawings, in which Figs. la and 122, when joined together end to end, present a side elevational view of a complete apparatus in which the confections are coated, decorated and coo-led and in which the decorations, once formed, are preserved until the coatings of the confections have hardened;

Fig. 2 is a sectional ele-vational view through the coating machine section of the apparatus; and

Fig. 3 is a cross sectional view taken on the line 3-3 of 2.

Figs. 4, 5 and 6 are diagrammatical views showing successive stages in the formation of a decorated confection;

Figs. 7, 8, 9 and 10 are plan views showing various decorated confections made by the apparatus; and

Figs. 11, 12, 13 and 14 are elevational views of the confections shown in Figs. 7, 8, 9 and 10, respectively.

Referring to Figs. 1a and 1b there is shown a preferred and complete form of apparatus for accomplishing the stated work, which apparatus includes a suitable coating machine A, a feed belt 7 therefor, a delivery conveyer (l, a suitable cooling means, as the cold box C. and a tunnel T which connects the casing of machine A to the cold box. The conveyer (Z, in its confection-carrying stretch, extends through the coating machine casing A, through tunnel T and through cold box C. This particular form of cooling means is not necessarily essential and is given merely as an illustrative example of one of many means which are suitable for the purpose and are known and available to the trade.

to Fig. 2, confections placed on el to the right and are transferred in the usual way to the previous coating machine belt 142, usually of wire mesh. They are coated in the usual manner. For example, chocolate or any other suitable coating material flows downwardly in a transverse sheet from shower pan 3 and envelops the tops and sides of the confections. Rolls 1", located beneath the upper stretch of coating belt w, pick up some of the chocolate, which passes through the belt, and apply it to the bottoms of the confections. The excess coating is re moved from the confections by a blast of air delivered from a motor-driven blower b (Fig.

1a throu h a nozzle a. The coatin is en a e: a P

plled to pan 8 from a supply tank 2; (Fig. 3)

located in the base of casing A,being elevated therefrom by a pump p through a conduit 0. These coating means are to be taken as illustrative of one of many suitable coating means which are available for the purpose and, according to the broader aspects of the invention, the coating may be applied in any desired way.

The main condition, which is essential to the present invention, is to have the confections carried by some conveyer, whether it be the wire belt w or otherwise, at a time when the coatings are still soft and viscous and to have the conveyer carry the coated confections toward or to its lower stretch, so that they can drop, and by dropping, draw out decorative strings or markings from the coatings. The confections, as they drop from belt 10 fall upon delivery belt (Z which travels in the same direction and at the same speed as the lower stretch of belt w. Consequently, it is not important to have the confections drop from belt w at any particular pointor in any particular order. Whenever the confections do drop and at whatever point in the lower stretch or belt 11) (within the limits shown) there will be a free space on the delivery belt to receive them.

To secure this advantage and a reliable in surance against trouble due to superimposing or otherwise merging one confection with another, conveyer cl has to travel back through the casing A. This casing, as is customary, is heated and tank t is also heated (as evidenced by the jacket j provided therefor) in order to maintain the coating in fluid form. The decorations are formed on the confections while the coating is still soft although the coating is less fluid than at the time of its application to the confections. However, the coating which has been formed into a decorative marking, is still soft enough to be easily melted if again subjected to the temperature prevailing in casing A. Consequently, I provide a tunnel 10 through which conveyor d is arranged to pass and by which it is insulated from the heat of casing A. This tunned 10' extends from end to end of casing A but is of less width than the casing as shown in Fig. 3, leaving passages 11 through which excess coating can pass back by gravity flow into tank t. The tunnel may be formed in any suitable way but as shown it is formed by a double-walled, box-like structure of rectangular cross section. The inner and outer Walls 12 and 13 of the tunnel may bemade of sheet metal and the space therebetween filled with suitable insulating material 14. The tunnel is suitably supported from casing A, as by the cross bars 14 shown in Fig. 3.

The tunnel 1O communicates at one end with one end of the tunnel T. The latter is constructed similarly to tunnel 10. The other end of tunnel T communicates with the cold box O, the interior of which is maintained at low temperature. Consequently, cool air from the cold box willenter the tunnels T and 10, whereby the delivery conveyor is not only insulated from the heat of easing A but is also positively cooled, the more effectually to preserve the decorations.

The cold box illustrated is like that disclosed in my U. S. Letters Patent No. 1,667,765, granted May 1, 1928, and need not be described in detail. It will suffice to state that the cold box contains suitable provisions for cooling the confections and affords a long tunnel (much of it is broken away in the drawings) through which belt d travels. As the confections emerge from the left hand end of cold box C (Fig. 1b) the coatings are thoroughly hard.

The belt cl, as herein shown, is of reenforced waxed paper. In its upper stretch it extends from an end roll 15 shown in Figs. 1a and 2, to an end roll 16 shown in Fig. 1b, and is suitably supported, as by the table 17 while travelling through tunnel 10, by a table 18 while passing through the tunnel T and by similar means (not shown) while travelling through the cold box. Belt (5 is driven by frictional contact with a belt 19, such as a canvas belt, which underlies the belt (2 during its travel through the cold box. The belt cl is tensioned and drawn against belt 19 by the weighted idler 20 (Fig. 1b) and the weight of the confections on the belt (Z contributes in maintaining sufficient frictional engagement between these belts for the driving function. Belt 19 extends between end rolls 21 and 22 and is driven from the latter roll by means of a worm gear 23, a worm 24 and shaft 25, which extends to the coatingmachine and is driven therefrom, as by a chain 26 which connects it through a speed change mechanism 27 to a suitable source of power exemplified in part by the pulley 28. Underlying the return stretch of travel of belt d through the cold box G is the upper stretch of a belt 29 which is driven by a roll 30, worm gear 31 and worm 32 from shaft 25. Both belts 19 and 29 are provided with weighted tension rolls 33 and 34, respectively.

The feed belt 7 in its upper stretch travels over a table 35 which is supported at one end at 36 from casing A and at the other end at 37 from brackets 38 on cold box C,-both these supports being of a nature such as to permit easy movement of removal of the table. Belt f has a driving roll 39 mounted in brackets 38 and this roll is driven by a chain 40 and suitable sprockets from roll 30, above described.

The wire belt w is trained between two en rolls 41 and 42, both of small diameter, and supported at intermediate points in its upper stretch of travel by rolls 1 and a series of rolls 43. This belt is driven by a roll 44 and this roll and a roll 45 guide the lower stretch ofbelt, to so that it scrapes along the bottom 46 of a trough, the-side walls of which are designated 47. At one end this trough is provided with a sump 48 and the wire belt w in dragging along the floor of trough 46 carries all excess chocolate dripping through the belt back to sump 48. This sump has an outlet 49 at each side and associated with the outlets are spouts 50 which direct the chocolate into the described spaces 11. A screw 51 rotatably supported at its ends from casing A revolves in sump 48. One half of the screw is of opposite pitch from the other half and this arrangement combined with proper direction of rotation of the screw, as shown in Fig. 8, serves to force the chocolate from the center in opposite directions towards outlets 49. Thus, the excess chocolate is co1- lected and returned along opposite sides of the delivery belt into tank t. The floor .46 and sump 48 of the trough are provided with a jacket 47 in which a heating medium is circulated.

The screw 51 is driven by a chain 52 and suitable sprockets (Fig. 1a) from a stub shaft 53 which in turn is connected by bevel gears 54 to a shaft 55. The latter is driven by a wrocket chain 56 from a short shaft 57,

which in turn is driven by a sprocket chain 58 from the described shaft 25. The various rolls 1", 43, 44 and 45 are interconnected by an approximately horizontally disposed train of spur gears 59, one member of which is driven by spur gears 60 from a stub shaft 61, which in turn is driven by bevel gearing 62' from the described shaft 55. The end rolls 41 and 42 aredriven by sprocket chains 63 and 64, respecti\*ely,fro1n members of the gear train 59.

The pump p is driven directly from the transmission 27. The tank 25 has a stirrer m which is driven by a sprocket chain 65 from the aforesaid transmission.

In decorating confections by the pecuiiar method of allowing them to drop from a belt and draw the coating out into a decorative marking, the distance through which the confections falls seems to have a critical influence so far as successful results are con- To this end, the table 1'? or the lower stretch of the wire belt 10 or both, as shown,

are arranged too-be moved toward and away from one another. The table 17 may, for example, be hinged at one end, as at 66 to casing A and provided at its other end with I suitable means whereby it may be raised and lowered. As shown, the table has secured to its under face brackets 67, through which a rod 68 extends. The ends of rod 68 are mounted in blocks 69, which slide in vertically disposed ways provided in a pair of side frames 7 O, secured to casing A. A screw 71, supported in each frame 70 for rotation but held against axial movement, is threaded through the adjacent block 69. The two screws are connected by a sprocket chain 72 so as to turn in unison and a crank 7 3 is provided on one or both of the screws to enable it conveniently to be turned. Thus, table 17 may be raised toward or lowered away from the lower stretch of belt to. The end roll 42 for wire belt w is mounted in a bracket 74 which is connected for longitudinal adjustment by bolt and slot connections 75 to a bracket 7 6. This adjustment is primarily for belt tensioning purposes. The brackets 76, however, are connected to side frames 70 for vertical adjustment, as by bolt and slot connections 77, whereby the end roll 42, and thus the section of belt w between it and roll 45, can be raised or lowered. This ad justinent also serves to change the slope of that range of the lower stretch of the wire belt over which the confections drop, and this slope in some cases seems to have an influence on the character of the decorative markings produced.

In operation, the confections to be coated and decorated are placed on feed belt 35 in any suitable manner. Belt 35 carries the confections to and transfers them to the wire belt w. As the confections travel along with beltw, in the upper course of its travel, they arecoated in part by passing through a descending stream of coating falling from shower pan 8 and in part by the action of rolls 7, which act to force chocolate up through the meshes of belt 10 and coat the bottoms of the confections. The confections, now completely coated, neXt pass under the nozzle 11. and are subjected to an air blast from the same, whereby some of the applied coating is removed. The above, is the usual coating operation.

The coated articles continue to travel with belt w for a short time after the latter enters its lower course of travel because the coatings of the confections which are still plastic, cling to the wires of the wire belt to. The confection, if a bonbon coated. with fondant, such as shown at 78 in Fig. 4, may contact with three wires of the belt to. If the confection is a smaller one, such as a peanut or raisin, coated with chocolate there may be only one or two lines of contact with belt w. In any event, the confection now travelling upside down, is suspended by its plastic coating from one or more wires ofbelt w and commences to fall, thereby drawing out the coating in one or more strings 7 9 (Fig.

5). The confections continue to fall and the strings 79 continue to be drawn out until they break, whereupon the confection drops upon belt (Z and the strings 79 fall back on the con fection in various ways forming decorative markings, such as shown at 80 in Fig. 6. Generally, the confection, if a bonbon, has the shape of a ball and has no fiat bottom face and, of course peanut-s and raisins have no flat oottom face. Such flat bottom face is formed when the confection strikes on belt cZ,-the blow serving to flatten out the still plastic coating into a. well defined flat bottom face 81.

It is dihicult to describe with any more accuracy the formation of the decorations because they are not regular and uniform and according to a predetermined pattern. The very irregularity and non-uniformity-of the decorations is what makes them more attractive. However, in Figs. 7 to 14, I have shown several specimens of decorations formed on bonbons (ball shaped centers coated with fondant) and these figures will serve to illustrate some of the various decorations which actually have been made with the apparatus. Many other styles of decorations may be effected and it is not feasible to illustrate all forms possible to obtain. In all of the four examples illustrated, one may readily trace the results of the three lines of contact with the wire belt w. Thus in Fig. 10, three distinct parts 82 of the coating have been drawn up. Such parts start with a comparatively wide base and taper upwardly into a string and the several strings have here merged into a single one 83, which has fallen over one side of the confection. In Fig. 9, the several strings 82, did not merge but in falling back on the confection crisscrossed, forming quite a d fferent decoratlon. In Fig.

7, the tail ends 84 of the strings fell back almost at right angles to the thicker body portion 85 thereof. Fig. 8 is much like Fig. 10 except that the decoration is located near one side of the confection rather than centrally thereof, as in Fig. 10. It will thus be seen that it is difiicult to predict just what the decoration will be except that it will show one or more strings which have been drawn up from the coating and which fall back in various ways and produce different effects. With chocolate coating which is less viscous, the strings will be shorter and the decorations will not be as pronounced as those here shown.

In some cases, as for example in bonbonwork, where a fondant coating is applied, relatively heavy confections can be decorated by the method described because the coating is thick and gummy and will support these confections for the necessary short interval during which they are being inverted. A confection of this kind will usually drop shortly after it turns around end roll 42. In

such case, the confection when it falls would also have a tendency to rotate. Accordingly, if the confection has a fiat bottom, it is necessary to adjust the distance through which such a confection falls so that it will land with its flat face on belt at. That is, the distance should be such that the confection would be stopped by belt d after it had turned through half of a revolution.

With smaller centers, such as peanuts and raisins, which have no flat faces, the distance between the belts d and w nevertheless needs to be varied, although not for the reason just given, if uniformly successful results are to be obtained. If this distance is too great, too long, a string may be formed. If it is not great enough, the string drawn out may not break during the fall of the confection. The adjustment enables variations in the lengths of the strings and this enables variations in the designs produced. Also, the slope of belt w seems to have an effect on the character of the designs produced. If the slope is steep,

the strings tend to fall rearwardly on the con fections whereas if it is not, the strings tend to stand up on the confections. It is difiicult to describe with accuracy just what results will follow from the adjustments of distance of drop and of the slope of belt w because the results in each case depend on so many factors which are variable, such as the size, shape, and weight of the centers and the kind, character and viscosity of the coating. It is a fact, nevertheless, that I have found that w these adjustments do enable me to control the formation of decorations and to vary the character of the same, wherefore I deem such adjustments essential to the practice of the method of decoration above set forth.

The features of invention relating to the preservation of the decorations, once they have been formed, such as the insulating means and the cooling means for the delivery conveyer, and the features of invention relat to the collection and return of excess chocolate may, however, be used independently of each other and independently of the provisions for controlling the formation of the decorations.
